Technic pneumatic tow truck "Pneumayhem"

I am in the finishing stages of building my version of a heavy duty tow truck, trying to make a model with a high level of platability, without using any electric parts at all. At first I just tried to make an 8x4 chassis with full independent suspension (double wishbone on the front two axles, and Live axle for the rear two axles. The below picture is close to the final result, but some modifications have been made as I went along, including a differential between both driven axles (located more or less amidships), and more springs in the front to support the massive weight.

This is not a complete presentation, as the truck isn't finished yet, more of a teaser of some of the functions (mostly pneumatic) and features of the model.

The cab, is loosely based on the one from the beloved 8258 Crane Truck, however the roof is a design of my own, as is the grille and also a lot of other details, as later pictures will show.

The above picture shows the truck in a more or less completed state, but several improvements have been made since this picture was taken.

The above image shows the front sans cab, with the pneumatic air tank, and the two manual pumps.

Minor changes have been made, amongst others a pneumatic cylinder to facilitate lifting of the cab.

Here you see the improved cab, featuring opening doors and a better looking front assembly thingy.

You can also see parts of the self sustained automatic electric compressor unit, that can be placed inside the cab instead of the seats and steering wheel. It is then connected to the pneumatic circuit, and will maintain pressure, without having to use energy yourself.

A closer view of the rear outriggers, towing fork and small winch, as well as the main boom lifting cylinders. The boom extention is via a crank on the right hand side of the chassis. it drives a worm gear in the main boom, through an intricate system of axles and gears from the chassis.
